Hi I am trying to save data from a form to Student model; abstract User model.
Please help!
PROBLEM: IntegrityError at /register/ UNIQUE constraint failed:
accounts_students.username
Not sure what the problem, in the view i am trying to clean the data and save it to the database.
Interestingly, the data is being saved, just the page is not being
redirected!

Im registering succesfully user, but when ot redirects me to login page I'm 100% sure password is correct, but it is not login me in, so I checked the admin page for that particular user, username exists, but it says that the password is not created yet.
this is my views.py

Please suggest some solution. I was following Corey Schafer tutorial.
Try to read about django.contrib.auth and passwords.
https://docs.djangoproject.com/en/4.1/topics/auth/default/#changing-passwords
Django don't change password to hash, you should do it yourself before user.save()
in your case:
... # your staff
form = UserRegisterForm(request.POST)
if form.is_valid():
user = form.save(commit=False)
user.set_password(form.cleaned_data['password'])
user.save()
username = user.username
messages.success(request, f'You are now able to log in!')
... # other staff
I am trying to have a user register, and then log in. Once they are logged in they specify their WiFi name, followed by a wifi password, and their choice of a VPN. The problem I am having is hashing the wifi_password field upon saving it to the database. I am trying to hash the password within the edit function in views.py. I have posted the entirety of my models, forms, and views. The code is still sloppy, and will need some cleaning up when I can achieve functionality. Thanks.

But if you will hash the password yourself, you will need to override authenticate as well as the Django won't be able to regenerate the hash to find the user record
I need to display the details of the user on the profilepage. But in the following situation, I am unable to render phone number and flag(attributes of SpecialUser model) on my profile page. I was asked to implement an extended model for the User model in Django auth for an application. I introduced 2 new fields i.e, phonenumber(charfield), flag(booleanfield). My form is able to take both the inputs. But I couldn't render these values again into my HTML file. Could someone help me out!

The models file:

return self.title + f" ({self.rel_user.username})"
The forms file:
from django.forms import ModelForm
from Books.models import Book
class BookForm(ModelForm):
class Meta:
model = Book
fields = ['title', 'description', 'price', 'state', 'city', 'neighbourhood', 'phone']
The views file:
from django.shortcuts import render, redirect
from Books.forms import BookForm
from django.contrib import messages
def sell(request):
if request.method == "GET":
form = BookForm()
else:
form = BookForm(request.POST, )
if form.is_valid():
form.save()
messages.success("Successfully added!")
return redirect('sell')
else:
messages.error("Please fill in all the fields.")
return render(request, 'Books/sell.html', {"form": form})
Every time a user submits the form, I want the ForeignKey's value to be filled with that users model. How do I do this?
So suppose user "John" has filled the form. When he clicks submit, the details he enters + his user model should go into the database for that entry.
def sell(request):
if request.method == "POST":
form = BookForm(request.POST)
if form.is_valid():
instance = form.save(commit=False)
instance.rel_user = request.user
instance.save()
messages.success("Successfully added!")
return redirect('sell')
else:
messages.error("Please fill in all the fields.")
else:
form = BookForm()
return render(request, 'Books/sell.html', {"form": form}
request.user can be assigned to rel_user as above
You can assign the user to the instance of the form:
from django.shortcuts import render, redirect
from Books.forms import BookForm
from django.contrib import messages
def sell(request):
if request.method == 'GET':
form = BookForm()
else:
form = BookForm(request.POST)
form.instance.rel_user = request.user
if form.is_valid():
form.save()
messages.success('Successfully added!')
return redirect('sell')
else:
messages.error('Please fill in all the fields.')
return render(request, 'Books/sell.html', {'form': form})
This question already has answers here:
How to automatically login a user after registration in django
(6 answers)
Closed 7 years ago.
In django 1.9, how do you automatically log in the user after they have registered?
I followed the answer from this question, but I get this error when trying it out.
I added AUTHENTICATION_BACKENDS = ('django.contrib.auth.backends.ModelBackend',) to settings.py
Here is my views.py:
from django.shortcuts import render
from django.views.generic.edit import CreateView, UpdateView, DeleteView
from .models import UserProfile
from django.contrib.auth.models import User
from .forms import UserForm
from .forms import UserProfileForm
from django.http import HttpResponseRedirect
from django.contrib.auth import authenticate, logout, login
# Create your views here.
def RegisterView(request):
registration_success = False
if request.method == 'POST':
user_form = UserForm(request.POST, prefix='uf')
profile_form = UserProfileForm(request.POST, request.FILES, prefix='upf')
if user_form.is_valid() and profile_form.is_valid():
user_atr = user_form.save()
user_atr.set_password(user_atr.password)
user_atr.save()
profile = profile_form.save(commit=False)
profile.user = user_atr
profile.avatar = request.FILES.get('avatar')
profile.save()
registration_success = True
user_atr = authenticate(username=request.POST['username'],
password=request.POST['password'])
login(request, user_atr)
return HttpResponseRedirect("/")
else:
print (user_form.errors, profile_form.errors)
else:
user_form = UserForm(prefix='uf')
profile_form = UserProfileForm(prefix='upf')
return render(request, 'profile/register.html', {'profile_form': profile_form, 'user_form': user_form})
And my forms.py:
class UserForm(ModelForm):
def __init__(self, *args, **kwargs):
super(UserForm, self).__init__(*args, **kwargs)
for field_name, field in self.fields.items():
field.widget.attrs['class'] = 'field-input-element'
confirm_password = forms.CharField(widget=forms.PasswordInput())
class Meta:
model = User
fields = ('username', 'email', 'password')
widgets = {
'password': forms.PasswordInput(),
}
class UserProfileForm(ModelForm):
def __init__(self, *args, **kwargs):
super(UserProfileForm, self).__init__(*args, **kwargs)
for field_name, field in self.fields.items():
field.widget.attrs['class'] = 'field-input-element'
class Meta:
model = UserProfile
fields = ('display_name', 'avatar', 'birthday', 'usertype', 'daw', 'usergenre', 'gender')
widgets = {
'birthday': AdminDateWidget(),
}
You are using a prefix for your form, so the data will be posted as uf-username and uf-password. Therefore request.POST['username'] gives a KeyError.
It's not normally a good idea to fetch data directly from request.POST anyway. Fetch it from the form's cleaned data instead, and let Django take care of the prefix and validation.
user_atr = authenticate(username=user_form.cleaned_data['username'],
password=user_form.cleaned_data['password'],
)
